PIPE CONNECTION.

Original application filed February 11, 1916, Serial No. 77,591.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Divided and this application filed. June 19,

1916. Serial No. 104,393.

To all whom it may concern:

Be it known that I, HENRY DEITZ, a citizen of the United States, and aresident of Denver, in the county of Denver and State of Colorado, haveinvented a certain new and useful Improvement in Pipe Connections, ofwhich the following is a full, clear, and exact description.

This invention is an improvement in devices for connecting a smallerpipe to a larger one, said pipes being so arranged that a current of airin the larger pipe will serve to draw a gas or vapor through the smallerpipe into the larger by an injector action.

My device is especially adapted for use in connecting an auxiliarysource of steam or moist air to the intake pipe of a carbureter of aninternal combustion engine.

The principal object of my invention is to so design the device that itmay readily be connected to and disconnected from the intake pipe of acarburetor and that the maximum injector action will be obtained.

A second object is to provide a device of the character described whichwithout change will be capable of attachment either to an open intake orto one where the air supplied to the carburetor comes from heatingmeans, as the case may be.

Further and more particular objects and advantages of my invention willlater appear from this specification.

In the single sheet of drawings accompanying this application andforming a part hereof Figure 1 is a side view of one form of myinvention as applied to a closed-end intake pipe; Fig. 2 is a crosssection through Fig. 1 taken on the line 22 of that figure; Fig. 3 is a.broken away side view of the same modification of my invention as shownin Figs. 1 and 2 illustrating it as applied to an open-end intake pipe;and Fig. 4 is a central section on a somewhat larger scale through amodified form of my invention.

The subject matter of Figs. 1, 2 and 3 of this application was disclosedin a previous application for patent filed by me on February 11, 1916,Serial Number 77,591 from which application said matter had beendivided, and this application is a continuation of that application inrespect to all common subject matter.

The preferred form of my invention shown in Figs. 1, 2, and 3 is What Iterm a universal connection in that the same connec tion is adapted foruse either with an openend pipe or with one where an opening must bedrilled in the intake. This connection comprises a tubular body member 5bent at right-angles at its lower end to extend as shown substantiallyon the axis of the pipe to which it is to connect. In its upper end themember 5 has a socket for the reception of a section of flexible tubing6 which connects to the source of steam or moist air and which isretained in its socket by the set screw 7. 'About midway down itsvertical portion the member 5 has a cylindrically curved cape 8, thecurvature given the cape 8 being such as to coincide with the curvatureof the pipe to which the connection is to be made, the cape beingprovided adjacent its lower straight edges with slots or other attachingmeans 9. Above the cape the member 5 also carries a radially projectinglug 10 which is tapped for the reception of a set screw 11. If desiredthis connection may be inserted through an opening made in the intakepipe and this manner of mounting it is illustrated in Figs. 1 and 2. Soplaced the lower end 12 of the member 5 extends substantially into thecenter of the intake pipe, thus increasing the efficiency of theinjector action, and the cape 8 fits down on the exterior of the pipe Pand seals any space which may be left unfilled by the member 5. Thedevice is then secured in position by a soft metal strip or the like 13which is passed through the slots 9 and bent down to hold the partssecurely in place. In this use the lug 10 and the set screw 11 are idle.If, however, it is desired to attach the device to a car having anopenend intake pipe P the same connection may be employed withoutchange, as illustrated in Fig. 3. Here the cape 8 is set against theinterior, of the pipe P and the pipe is grasped between the cape and thelug 10, the set screw 11 firmly holding the parts in position. In thismounting the strap 13 is not required.

In Fig. 4 I have illustrated a modification of my device applicable onlyto cars with the open-end intake. In general outline the body member 14of this form is similar to the body 5 of the previous modification andit has a lug 15 and set screw 16 corresponding to the lug 10 and screw11. But in this form the cape 8 is replaced by a curved surface 17 onthe front side of the body member 1 1 only. This form of my device isapplied to the intake in the same manner as shown in Fig. 3, the pipe Pbeing grasped between the face 17 and the set screw 16.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. In a device of the class described, a tubularmember, an outer surface thereon curved in conformity with the curvatureof the pipe to which the device is to be secured, a lug extendingradially from said tubular member above said surface, and a set screw insaid lug.

2. In a device of the class described, a tubular member having its lowerend bent at right angles to the body portion thereof, an outer surfaceon the upper portion of said tubular member curved in conformity withthe curvature of the pipe to which the device is to be secured, a lugextending radially from said tubular member above said surface, and aset screw in said lug.

3. In a device of the class described, a tubular member, a cape thereoncurved in conformity with the curvature of the pipe to which the deviceis to be secured, said cape being provided with slots located adj acentits straight edges, a lug extending radially from said tubular memberabove said cape, and a set screw in said lug.

4. In a device of the class described, a tubular member, having itslower end bent at right angles to the body portion thereof, a cape onsaid tubular member curved in conformity with the curvature of the pipeto which the device is to be secured, said cape being provided withslots located adjacent its straight edges, a lug extending radially fromsaid tubular member above said cape, and a set screw in said lug.

In testimony whereof I have hereunto affixed my signature.

HENRY DEITZ.
